Arsenal boss Unai Emery accepted supporters' jeers for hooking Alexandre Lacazette during victory over Fulham.

Lacazette had put Arsenal two goals in front following Granit Xhaka's opener but was substituted for Aaron Ramsey after Aboubakar Kamara had halved the deficit.

The decision was booed by a large number of fans, although Ramsey put the game beyond doubt with the third.

"I understand the supporters," he said.

"Tactically we thought in that moment we needed to change for more balance. Above all we know (Jean Michael) Seri is coming on and need a player close to him, not to let him play easily with the ball.

"Aaron Ramsey can do that and also help us in attack and scored. The reason is this. I need to do my work. And not maybe because every supporter can have a different opinion, tactically.

"But I need to do my work, Lacazette his work and he scored also. He helped us and it was a very positive reaction."
